Description

本発明は、縦型およびドラム式洗濯乾燥機、全自動洗濯機の槽洗い制御に関する。   The present invention relates to tank washing control of vertical and drum-type washing and drying machines and fully automatic washing machines.

トイレマットや台所マットなど(通常の洗濯物と異なり頻繁に洗濯しないもの)や、ペット用のタオルや服など、通常の洗濯物と分けて洗いたいものがある。さらに、それらを洗った後に、続けて通常の洗濯物を洗濯することに抵抗を感じる方がおり、中には、一度槽を洗ってから、通常の洗濯物の洗濯を行う方がいる。   There are things that you want to wash separately from regular laundry, such as toilet mats and kitchen mats (those that do not wash as often as ordinary laundry), and towels and clothes for pets. Furthermore, after washing them, people may feel resistance to continuing to wash normal laundry, and in some cases, it is better to wash the tank once and then wash normal laundry.

その場合、バケツやホースで槽内に水をかけようとすると、水が飛び跳ねたり、あやまって洗濯槽の外に水を垂らしてしまい、床を濡らす恐れがあるため、手動設定で槽内に水をためて洗ったり、あるいは、抵抗を感じながらも、仕方なくそのまま通常の洗濯物の洗濯を行っている。   In that case, if you try to pour water into the tank with a bucket or hose, the water may jump up or fall out of the washing tank, which may cause the floor to get wet. Even if I was able to store and wash or feel resistance, I was forced to wash the usual laundry as it is.

従来より、文献1(特開2004−141344)のように、外槽と、外槽の内側に回転可能に支持された内槽を備え、内槽の内部に洗濯物と洗濯液を一緒に入れた状態で行なう洗い運転と、洗い運転の終了後内槽および外槽の内部から洗濯液を排出する排水運転と、排水運転後洗濯物を水洗いするすすぎ運転と、すすぎ運転後内槽を回転させて遠心力により洗濯物の水分を振切る脱水運転を行う洗濯機において、洗濯槽を掃除するコースがある。   Conventionally, an outer tub and an inner tub rotatably supported inside the outer tub are provided as in Document 1 (Japanese Patent Laid-Open No. 2004-141344), and the laundry and the washing liquid are put together in the inner tub. The washing operation performed in a steady state, the drainage operation discharging the washing liquid from the inside of the inner tank and the outer tank after the washing operation, the rinsing operation washing the laundry after the drainage operation, and the inner tank rotating after the rinse operation There is a course in which the washing tub is cleaned in a washing machine which performs a dehydration operation to shake off the moisture of the laundry by centrifugal force.

また、コインランドリー式全自動洗濯機において、コイン投入後10秒以内にボタンを押して槽内を洗う工程を選択すると、約20秒間槽を回転させながら、シャワー給水を行い、洗濯槽を洗い(所要時間:約50秒)、その後ロック解除して、洗濯物と洗剤を入れて洗濯を行うものがある。   In addition, in the coin laundry type fully automatic washing machine, if you select the process of washing the inside of the tank by pressing the button within 10 seconds after coin insertion, shower water is supplied while rotating the tank for about 20 seconds to wash the washing tank (required time : About 50 seconds), then unlock and put laundry and detergent to wash.

特開2004−141344Patent document 1: JP-A-2004-141344

洗濯機がすべてをキレイにしてくれるので、全部一緒に洗濯しても気にならない方もいるが、トイレマットと顔をふくタオルを分けて洗いたい方、ふきんと靴下を分けて洗いたい方、ペット用タオルと人間用タオルを分けて洗いたい方など、一緒に洗濯したくないものがある方もおり、その分け方は千差万別である。さらに、トイレマットと通常の洗濯物を分けて洗う方たちの中で、通常の洗濯物を洗った後にトイレマットを洗濯することは問題ないが、トイレマットを洗った後の洗濯機に通常の洗濯物を投入することに抵抗を感じる方がいる。実際に槽内が汚れていなくても気分的に洗いたい場合と、トイレマットから出た細かい土砂や髪の毛が槽内に残っているのを見てテッシュペーパーで取り除いた後、サッと洗いたい場合などがある。   The washing machine cleans everything up, so some people don't mind if you wash them all together, but if you want to wash the toilet mat and towel separately, or if you want to wash the washcloth and socks separately, There are also people who do not want to wash them together, such as those who want to separate and wash pet towels and human towels, and there are a wide variety of ways to divide them. Furthermore, it is safe to wash the toilet mat after washing the usual laundry among those who separately wash the toilet mat and the normal laundry, but it is common to the washing machine after washing the toilet mat Some people feel resistance to putting in laundry. Even if you really want to wash it in the tank, even if it is not dirty, or if you want to wash it quickly after removing it with tissue paper, seeing that the fine earth and sand and hair from the toilet mat remain in the tank, etc. There is.

現状では、気分的なものに対しては、実際に汚れていないため、多少抵抗を感じながらも、特に対応はせずにそのまま次の洗濯を行ったり、人によっては手間がかかるが、無負荷で水をためて槽を洗い脱水した後に次の洗濯を行う場合もある。また、実際の汚れに対してはテッシュペーパーで拭き取ったり、水をかけて汚れを流して排水したり、水をためて槽を洗ったりするなどの対応が考えられる。   At present, the mood is not actually soiled, so while feeling some resistance, it does not take any action, and it does the next washing as it is, depending on the person it takes time, but no load In some cases, the next washing may be performed after washing the tank with water and dewatering. In addition, it is possible to take measures such as wiping off with a tissue paper, pouring the water on the soil for drainage, draining the soil, and washing the tank with water.

槽を洗うための既存のコースについて、所要時間が長すぎると判断した場合は手動で設定する必要がある。その際、現状の動作では水を溜めないと槽壁を洗うことは不可能であり、高水位まで水を入れるとなると、多くの水を使う上、水を溜めるための時間もかかる。   If it is judged that the time required for the existing course for washing the bath is too long, it is necessary to set it manually. At that time, it is impossible to wash the tank wall without storing the water under the current operation, and when it is filled with water to a high water level, it takes a lot of water and takes time to store the water.

また槽を洗う機能が、現状のコインランドリーに搭載されているように、洗濯を行う前に実行することを選択するという方法は、不特定多数の方が使用するコインランドリーでは、自分の洗濯物を投入する前に、どのような洗濯物を洗ったのかが不明な槽をいったん洗って、それから洗濯物と洗剤を投入するという方法は有効であるが、各家庭での洗濯機は必ずしも洗濯する直前に槽を洗う必要はなく、通常の洗濯物より汚れがひどいと思われるものを洗った後に槽を洗う方が使い勝手がよい。さらに、槽洗いをするか、しないかの判断は人それぞれであり、よって洗濯のサイクルの中に組み込まれているのではなく、1つのコースとして確立されているのが望ましい。   In addition, as the washing function is installed in the current laundromat, the method of choosing to carry out before washing does not charge your own laundry in the laundromat used by an unspecified number of people. It is effective to first wash the bath where you do not know what kind of laundry was washed, and then put in the laundry and detergent, but the washing machine in each home is not always just before washing There is no need to wash the tank, and it is more convenient to wash the tank after washing anything that seems to be more dirty than normal laundry. Furthermore, it is desirable for each person to decide whether or not to wash the bath, and thus to be established as a course rather than being incorporated into the wash cycle.

本発明は、上記の課題を解決するもので、汚れが付着していたり、あるいは気分的に通常の洗濯物と一緒に洗いたくないもの(トイレマットなど)の洗濯後、少ない水で短時間で槽内を洗うものである。   The present invention solves the above-mentioned problems, and after washing of things (such as toilet mats) which do not want to be soiled or moody to be washed together with ordinary laundry, in a short time with less water It is to wash the inside of the tank.

本発明は、その一例として、筐体と、前記筐体内に防振支持され、内部に洗濯水を貯留する外槽と、前記外槽内に回転自在に支持され、洗濯物が収容される洗濯兼脱水槽と、前記洗濯兼脱水槽を回転駆動させる駆動装置を備え、洗い、すすぎ、脱水の各工程の実行を制御する制御手段を備える洗濯機において、前記制御手段は、コースが選択された場合、前記洗濯兼脱水槽を回転させながら、給水を行うことで、パルセータおよび槽内に水をかけて、槽内洗い工程を実行する。   As an example of the present invention, a case, an outer tub supported in a vibration-proof manner in the casing, an outer tub for storing washing water therein, a rotatably supported in the outer tub, and a laundry in which the laundry is accommodated In the washing machine, the washing means includes a spin tub, and a driving device for rotating the washing spin tub, and includes control means for controlling the execution of the washing, rinsing, and dewatering steps, wherein the control means has a course selected. In this case, water is supplied to the pulsator and the tank by supplying water while rotating the washing and dewatering tank, and the in-tank washing process is performed.

本発明によれば、実際に槽に微小な泥等ゴミが付着している場合や、トイレマット等頻繁に洗濯しないもので洗濯機使用後に通常の洗濯物を投入するのに抵抗を感じる場合に、簡単な操作で槽内を洗うことができる。さらに、使用水量も抑え、比較的短い所要時間で洗うことができる。   According to the present invention, when dirt, such as small mud, actually adheres to the tank, or when it feels resistance to throw in a normal laundry after using the washing machine with something that does not wash frequently such as a toilet mat You can wash the inside of the tank with a simple operation. In addition, the amount of water used can be reduced and the washing time can be relatively short.

ステップS403
まず、洗濯兼脱水槽8の内側底面にある回転翼8aを回転駆動させて洗濯兼脱水槽8内の負荷有無の検出を行い、負荷有と判断した場合はエラー表示を出し、運転を行わない。これは、洗濯兼脱水槽8内に衣類が入ったまま給水しながら高速で回転させるとアンバランスになりやすく危ない状態になりやすいことと、また負荷により本来の目的である槽洗いができなくなるためである。
Step S403
First, the rotary wing 8a on the inner bottom surface of the washing and dewatering tank 8 is rotationally driven to detect the presence or absence of the load in the washing and dewatering tank 8. If it is determined that the load is present, an error is displayed and the operation is not performed. . This is because if it is rotated at high speed while water is supplied while the clothes are in the washing and dewatering tank 8, it is likely to be unbalanced and in a dangerous state, and the tank cleaning which is the original purpose can not be performed due to the load. It is.

洗濯兼脱水槽8内を問題なしと判断した場合、次のステップに進む。   If it is determined that there is no problem in the washing and dewatering tank 8, the process proceeds to the next step.

Step S404

ステップS405
クラッチ機構10bを脱水モードにし、モータ10aに通電し、洗濯兼脱水槽8と回転翼8aを一体で回転する。回転数は徐々に上昇させる。このとき槽内給水電磁弁を開弁して洗濯兼脱水槽8内に給水する。洗濯兼脱水槽8の回転数の上限は、水ハネが問題ないレベルで本体の可能な回転数が望ましい。例えば、開口部9fを覆うように内蓋9aが設けられている縦型洗乾機は1000r/min、内蓋9aのない全自動洗濯機は150r/minなどである。
Step S405
The clutch mechanism 10b is set to the dewatering mode, the motor 10a is energized, and the washing and dewatering tank 8 and the rotary wings 8a are integrally rotated. The rotational speed is gradually increased. At this time, the in-tank water supply solenoid valve is opened to supply water into the washing and dewatering tank 8. The upper limit of the rotation speed of the washing and dewatering tank 8 is preferably the possible rotation speed of the main body at a level at which water splash does not matter. For example, the vertical washer provided with the inner lid 9a so as to cover the opening 9f is 1000 r / min, and the fully automatic washing machine without the inner lid 9a is 150 r / min.

開口部9fを覆うように内蓋9aが設けられている縦型洗乾機における槽洗いの動作を表したものが図6である。(無負荷判定動作および嵌合動作は除く)
洗濯兼脱水槽8が回転すると、洗濯兼脱水槽8内部や洗濯兼脱水槽8と外槽9とのすき間に空気の流れが発生する。一つは洗濯兼脱水槽8の回転方向(円周方向)の流れであり,もう一つは洗濯兼脱水槽8の上下方向の流れである。上下方向の流れは,回転翼8aや洗濯兼脱水槽8の下面による遠心ファンのような作用により発生する。すなわち,洗濯兼脱水槽8内の空気は、回転翼8aのファン作用で回転翼8aに吸い込まれるように洗濯兼脱水槽8の中央を回転翼8aの中心に向かい下向きに流れ、回転翼8aの外周側に押し出され、洗濯兼脱水槽8の外周壁8cを上側に流れ、再度回転翼8aに吸い込まれるように循環する(矢印41)。この時、一部の空気は、洗濯兼脱水槽8の外周壁8cの貫通孔8bを通り、洗濯兼脱水槽8の外周面と外槽9の内周面とのすき間に流れる。また、回転翼8aの中心に向かった空気の一部は、洗濯兼脱水槽8の下面のファン作用で回転翼8aに設けた水抜きのための多数の小孔を通り洗濯兼脱水槽8の下面と外槽9の底面のすき間に出て、洗濯兼脱水槽8の外周面と外槽9の内周面とのすき間に流れる。そして、貫通孔8bからの流れと合流しながらこのすき間を上向きに流れ、槽カバー9bに当り、洗濯兼脱水槽8の略中央から回転翼8aに吸い込まれるように循環する(矢印42)。空気の流量は、洗濯兼脱水槽8の回転数が高いほど多くなる。
It is FIG. 6 which represented the operation | movement of tank washing in the vertical washing machine in which the inner cover 9a is provided so that the opening part 9f may be covered. (Excluding no load judgment operation and mating operation)
When the washing and dewatering tank 8 rotates, a flow of air is generated inside the washing and dewatering tank 8 or in the space between the washing and dewatering tank 8 and the outer tank 9. One is the flow in the rotational direction (circumferential direction) of the washing and dewatering tank 8, and the other is the flow in the vertical direction of the washing and dewatering tank 8. The flow in the vertical direction is generated by the action of a centrifugal fan by the lower surface of the rotary wings 8 a and the washing and dewatering tank 8. That is, the air in the washing and dewatering tank 8 flows downward toward the center of the washing and dewatering tank 8 toward the center of the washing and dewatering tank 8 so that the air in the washing and dewatering tank 8 is sucked by the fan 8a. It is pushed out to the outer peripheral side, flows upward on the outer peripheral wall 8c of the washing and dewatering tank 8, and circulates again so as to be sucked into the rotary wing 8a (arrow 41). At this time, a part of the air flows through the through holes 8 b of the outer peripheral wall 8 c of the washing and dewatering tank 8 and flows between the outer peripheral surface of the washing and dewatering tank 8 and the inner peripheral surface of the outer tank 9. In addition, a part of the air directed to the center of the rotary wing 8 a passes through a large number of small holes for water removal provided on the rotary wing 8 a by the fan action of the lower surface of the washing and dewatering tub 8. It flows out into the gap between the lower surface and the bottom surface of the outer tank 9 and flows into the gap between the outer peripheral surface of the washing and dehydration tank 8 and the inner peripheral surface of the outer tank 9. Then, it flows upward through this gap while joining with the flow from the through hole 8b, hits the tank cover 9b, and circulates so as to be sucked into the rotary wing 8a from the approximate center of the washing and dewatering tank 8 (arrow 42). The flow rate of air increases as the number of rotations of the washing and dewatering tank 8 increases.

洗濯兼脱水槽8は右回転の後左回転を行う。最高回転数は1000r/minとし、給水は左右ともに回転数上昇時に行う。給水の開始および停止タイミングは洗濯兼脱水槽8の回転数が0r/minから、800〜900r/minに到達するまでとする。洗濯兼脱水槽8が止まっていると、給水口9gから出た水は回転翼8aの外周側付近の表面に落下し、飛び跳ねた水の一部は外周壁8cの下部を濡らす。洗濯兼脱水槽8の回転数を高くしていくと、この飛び跳ねが激しくなり、外周壁8cの広い範囲に水が到達するようになる。さらに、上述したように、外周壁8cに沿って上向きに流れる空気により、水が上方に巻き上げられる。洗濯兼脱水槽8の回転数が高くなるほど水は外周壁8cのより高い位置まで到達するようになる。本実施例では、洗濯兼脱水槽8の回転数を800〜900r/minとしているが、水を外周壁8cの上部まで万遍なく行き渡るようするためである。また、回転数が高いほど、外周壁8cに当たる水の強さが高まり洗浄効果が高まるが、回転数を高くするほど、使用水量、所用時間および消費電力量が増加するため、洗浄効果との兼ね合いから、給水時の回転数の上限を800〜900r/minとしている。この槽回転数の上限については、洗濯兼脱水槽8の形状や大きさ、深さ、回転翼8aの形状などにより異なるので、本体によって適切化を図る必要がある。   The washing and dewatering tank 8 rotates to the left after rotating to the right. The maximum rotation speed is 1000 r / min, and water supply is performed when the rotation speed rises on both the left and right. The start and stop timings of the water supply are from 0 r / min to 800 to 900 r / min from the rotation speed of the washing and dewatering tank 8. When the washing and dewatering tank 8 is stopped, the water coming out of the water supply port 9g falls on the surface near the outer peripheral side of the rotary wing 8a, and part of the splashed water wets the lower part of the outer peripheral wall 8c. As the number of rotations of the washing and dewatering tank 8 is increased, this jumping becomes intense, and water reaches a wide range of the outer peripheral wall 8c. Furthermore, as described above, water is rolled up by the air flowing upward along the outer peripheral wall 8c. As the rotation speed of the washing and dewatering tank 8 is higher, the water reaches a higher position of the outer peripheral wall 8c. In the present embodiment, the rotation speed of the washing and dewatering tank 8 is set to 800 to 900 r / min, in order to spread water evenly to the upper part of the outer peripheral wall 8 c. In addition, the higher the rotation speed, the higher the strength of the water that hits the outer peripheral wall 8c and the higher the cleaning effect, but the higher the rotation speed, the more the water used, the required time and the power consumption. Therefore, the upper limit of the rotation speed at the time of water supply is set to 800 to 900 r / min. The upper limit of the tank rotational speed is different depending on the shape and size of the washing and dewatering tank 8, the depth, the shape of the rotary wings 8a, and the like.

このように、回転数が高いほど水の拡散の範囲が広がることから高めの回転数の方が有利といえるが、洗濯兼脱水槽8の回転数に伴い、水の当る強さの最も強い部分が移動するため、一定回転数のみで給水することは好ましくない。回転翼8a上の汚れや槽壁の下部の汚れもとるために0r/minから給水を開始する必要がある。さらに洗濯兼脱水槽8内のあらゆる箇所に均一に水をかけるためには、最低回転数と最高回転数のみでの給水ではなく、回転数を上げつつ給水していく必要がある。   Thus, the higher the rotation speed, the wider the range of diffusion of water. The higher the rotation speed, the better. However, with the rotation speed of the washing and dewatering tank 8, the strongest part of the water hit strength Because it moves, it is not desirable to supply water only at a fixed number of revolutions. It is necessary to start the water supply from 0 r / min in order to remove the dirt on the rotary wings 8a and the dirt on the bottom of the tank wall. Furthermore, in order to apply water uniformly to all parts in the washing and dewatering tank 8, it is necessary to supply water while raising the number of rotations instead of supplying water only at the minimum number of rotations and the maximum number of rotations.

なお、給水を停止した後すぐに洗濯兼脱水槽8の回転数を下げることはせず、一定回転数を保つか、または回転数を上昇させた後にモータ10aの通電を停止する。これは、槽内給水電磁弁を閉じて給水を停止しても、給水口付近の残水や、洗濯兼脱水槽8内に残水があるためであり、残水を利用して洗浄を行いつつ、洗濯兼脱水槽8内の残水を洗濯兼脱水槽8外に出しきった後にモータ10aの通電を停止し、槽回転を停止している。コース運転中は排水弁14を開弁したままとし常に排水状態とする。   The rotation speed of the washing and dewatering tank 8 is not reduced immediately after the water supply is stopped, and the constant rotation speed is maintained or the rotation of the motor 10a is stopped after the rotation speed is increased. This is because even if the water supply solenoid valve in the tank is closed and water supply is stopped, residual water in the vicinity of the water supply port and residual water in the washing and dewatering tank 8 are used to perform washing using the residual water. Meanwhile, after the residual water in the washing and dewatering tank 8 has been completely taken out of the washing and dewatering tank 8, the energization of the motor 10a is stopped and the tank rotation is stopped. During the course operation, the drain valve 14 is kept open to constantly drain water.

洗濯兼脱水槽8を右回りと左回りの両方行うのは、外周壁8cには糸くずフィルターや、シャワーケースによる凹凸があり、一方向の回転では、水の当らない箇所ができ、給水量や給水時間を増やしても汚れが残ってしまうことへの対応のためである。   The washing and dewatering tank 8 can be both clockwise and counterclockwise because the outer peripheral wall 8c has irregularities due to lint filter and shower case, and rotation in one direction results in places where water does not hit, water supply amount It is to cope with the fact that dirt will remain even if the water supply time is increased.

槽回転上昇時に給水するのは、下降時に給水した場合の汚れ落ちと比較すると上昇時の方が汚れ落ちがよいことと、槽回転下降時に給水すると回転数が落ちたときに取れた汚水が洗濯兼脱水槽8内に残ってしまうためである。   Water supply at the time of tank rotation rise is that soiling is better at rising as compared with soiling at the time of water supply at the time of descent, and when water is supplied at the time of tank rotation descent It is because it will remain in the dehydration tank 8.

また、洗濯兼脱水槽8の右回転から左回転に移行する際には給水を行う。これにより回転翼8a上に広く水がかかり、回転翼8a上のゴミの動きがよくなり、次の左回転開始時に、遠心力により回転翼8aの外側にゴミが出やすくなる。このタイミングでの給水を行わずに、左回転開始と同時に給水を開始した場合は回転翼8a上に十分に水がかからないうちに洗濯兼脱水槽8の回転数が上昇するため、回転翼8a上のゴミははりついたままになってしまう。   Also, when shifting from the right rotation to the left rotation of the washing and dewatering tank 8, water is supplied. As a result, water is widely spread on the rotary wing 8a, the movement of the dust on the rotary wing 8a is improved, and the dust tends to be discharged to the outside of the rotary wing 8a by the centrifugal force at the start of the next left rotation. If the water supply is started simultaneously with the start of the left rotation without supplying water at this timing, the rotational speed of the washing and dewatering tank 8 rises before the water is sufficiently applied to the rotor 8a. The rubbish will remain stuck.

さらに、この一連の動作により、洗濯兼脱水槽8に設けられた貫通孔8bから勢いよく排出された水は、洗濯兼脱水槽8の外側および外槽9の内側の洗浄も行い、その後洗濯水排水路15を通り洗濯機1の機外へ排水される。洗濯乾燥機で乾燥運転を行った後、外槽9の内壁面や洗濯兼脱水槽8に、乾燥時に発生した綿状の細かな糸くず(埃)が付着してしまう場合がある。この状態で次回洗濯を行うと、この糸くずが洗濯水に流れ出る。流れ出た糸くずの一部は糸くずフィルターで捕集されるが、衣類に付着してしまい衣類の仕上りを悪化させる場合がある。槽洗いコースは、上記のように洗濯兼脱水槽8の外側および外槽9の内側の洗浄も行えるため、乾燥運転で外槽9や洗濯兼脱水槽8の外側に付着した糸くずを除去することもできる。槽洗いコースで流された糸くずは糸くずフィルター内に溜まるため、槽洗いコース終了後、操作表示パネル7に糸くずフィルターの清掃を促す表示57(図5)を行うようにしてもよい。   Furthermore, with this series of operations, the water vigorously discharged from the through holes 8b provided in the washing and dewatering tank 8 also cleans the outside of the washing and dewatering tank 8 and the inner side of the outer tank 9, and then the washing water The water is drained out of the washing machine 1 through the drainage channel 15. After the drying operation is performed by the washing and drying machine, cotton-like fine lint (dust) generated at the time of drying may be attached to the inner wall surface of the outer tank 9 and the washing and dewatering tank 8. The next time the laundry is performed in this state, the lint flows into the washing water. Although part of the runoff waste is collected by the waste filter, it may adhere to the clothing and deteriorate the finish of the clothing. Since the tank washing course can also wash the outside of the washing and dewatering tank 8 and the inside of the outer tank 9 as described above, the lint adhering to the outside of the outer tank 9 and the washing and dewatering tank 8 in the drying operation is removed. It can also be done. Since the lint left in the tank washing course is collected in the lint filter, a display 57 (FIG. 5) may be displayed on the operation display panel 7 prompting the cleaning of the lint filter after the tank washing course is completed.

なお、給水方法は、図7に示すように水圧別(流量別)で変えてもよい。これにより水圧によらず使用水量を一定範囲内に抑えつつ、汚れ落ちも一定レベルを保つようにできる。水圧の高い(流量の多い)家庭では、間欠給水とし、ON時間を変えて使用水量を目標範囲内に抑え、水圧の低い(流量の少ない)家庭では連続給水とすることで、汚れ落ちのレベルアップを図る。水圧は、すすぎ時の給水所要時間から割り出した値を使うこととする。(初回にこの値がない場合は「流量9.0<χ≦12.0L/min」時の動作を行うなどで対応)
以上は、開口部9fを覆うように内蓋9aが設けられている縦型洗乾機の動作の一例である。
The water supply method may be changed according to water pressure (by flow rate) as shown in FIG. As a result, the amount of water used can be kept within a certain range regardless of the water pressure, and the dirt removal can be maintained at a certain level. Intermittent water supply is used in households with high water pressure (high flow rate), and the ON time is changed to keep the amount of water used within the target range, and continuous water supply in low water pressure (low flow rate) homes to reduce soiling levels. To improve The water pressure shall be the value derived from the water supply time required for rinsing. (If this value does not exist for the first time, the operation at "flow rate 9.0 <χ 2.0 12.0 L / min", etc. is taken)
The above is an example of the operation of the vertical washing machine in which the inner lid 9a is provided to cover the opening 9f.

一方、内蓋9aのない全自動洗濯機で洗濯兼脱水槽8を高速回転させながら給水を行うと、水跳ねにより、外蓋3の裏側や上面カバー2aの開口部2b回りに大粒の水滴(直径4mm程度以上)を付着させてしまったり、外槽9の外に水滴を飛ばしてしまったりなどして床面を濡らしてしまうという不具合が生じるため、洗濯兼脱水槽8の最高回転数を抑える必要がある。   On the other hand, when water is supplied while rotating the washing and dehydration tank 8 at high speed with a fully automatic washing machine without the inner lid 9a, large droplets of water (about the back of the outer lid 3 and around the opening 2b of the top cover 2a) The maximum rotation speed of the washing and dewatering tank 8 is suppressed because problems such as attaching a diameter of about 4 mm or more, splashing water droplets to the outside of the outer tank 9, and wetting the floor surface occur. There is a need.

洗濯兼脱水槽8の内径が500mm、深さが450mm程度の全自動洗濯機の場合、おおよそ150r/minを最高回転数として給水することで、水跳ねを抑えつつ、洗濯兼脱水槽8内を洗うことが可能となる。   In the case of a fully automatic washing machine having an inner diameter of 500 mm and a depth of about 450 mm, the washing and dewatering tank 8 is supplied with water at approximately 150 r / min as the maximum number of rotations, thereby suppressing splashing of water. It becomes possible to wash.

図8は、全自動洗濯機の内部構造を示すために筐体の一部および外槽を切断して示した右側断面図である。図2と同一符号は同一部分を表す。上面カバー2aの後ろ側に設けた給水ユニット12に接続された給水ボックス12aの底面には、ほぼ鉛直方向に開口した複数個の給水口12bが設けられており、流体バランサ8dの内周面8d1の内側近傍に水41が流下するようになっている。洗濯兼脱水槽8が回転すると、流体バランサ8dの内周面8d1に引きずられて内周面8d1近傍に円周方向の空気の流れが発生する。このため、給水口12bから流下する水41と内周面8d1との間のすき間8eの圧力が低下し、内周面8d1との距離が短い水41aは流体バランサの方向に曲げられる。洗濯兼脱水槽8をおおよそ150r/minで回転させると、流下する水41の一部41aが流体バランサ8dの内周面8d1にかかり、そこから外周壁8cに水が伝わり外周壁8cに沿って流下する。残りの水41は、回転翼8a上面の外周近傍に落下し、回転翼8aの上面を洗浄するとともに、飛び跳ねて外周壁8cの下部を濡らす。外周壁8cの上部から流下する水と飛び跳ねた水とで外周壁8cの洗浄が可能となる。外周壁8cにまんべんなく水が伝わるように、洗濯兼脱水槽8の回転数や給水時間、給水タイミング、さらには給水口12bの形状と合わせて調整するのがよい。   FIG. 8 is a right side sectional view showing a part of the housing and the outer tub in a cutaway view to show the internal structure of the full-automatic washing machine. The same reference numerals as in FIG. 2 denote the same parts. On the bottom surface of the water supply box 12a connected to the water supply unit 12 provided on the rear side of the upper surface cover 2a, a plurality of water supply ports 12b opened substantially vertically are provided, and the inner peripheral surface 8d1 of the fluid balancer 8d The water 41 is allowed to flow down near the inside of the. When the washing and dewatering tank 8 rotates, the flow of air in the circumferential direction is generated in the vicinity of the inner circumferential surface 8d1 by being dragged by the inner circumferential surface 8d1 of the fluid balancer 8d. Therefore, the pressure of the gap 8e between the water 41 flowing down from the water supply port 12b and the inner circumferential surface 8d1 decreases, and the water 41a having a short distance to the inner circumferential surface 8d1 is bent in the direction of the fluid balancer. When the washing and dewatering tank 8 is rotated at approximately 150 r / min, a part 41a of the flowing water 41 is applied to the inner peripheral surface 8d1 of the fluid balancer 8d, from which the water is transmitted to the outer peripheral wall 8c and along the outer peripheral wall 8c Flow down. The remaining water 41 falls in the vicinity of the outer periphery of the upper surface of the rotary wing 8a and cleans the upper surface of the rotary wing 8a and jumps to wet the lower portion of the outer peripheral wall 8c. The water flowing down from the upper portion of the outer peripheral wall 8c and the splashed water make it possible to wash the outer peripheral wall 8c. In order to uniformly transmit water to the outer peripheral wall 8c, it is preferable to adjust in accordance with the number of rotations of the washing and dewatering tank 8, the water supply time, the water supply timing, and the shape of the water supply port 12b.

図9は、洗濯兼脱水槽8の回転数の変化と給水タイミングを示す図である。洗濯兼脱水槽8を右回転で約100r/minまで増速し、その後回転の上昇速度を緩めて約150r/minまで回転を上昇させ、100r/minまで減速させる動作を複数回繰り返す。その後回転を止め、洗濯兼脱水槽8を左回転させ、右回転と同様に回転数を変化させる。給水は、洗濯兼脱水槽の回転数が100r/minから150r/minに上昇している最中に行う。縦型洗乾機の場合は最高回転数が800〜900r/minと高いため、回転翼8a上や洗濯兼脱水槽8の下部の洗浄を行うために停止状態(0r/min)における給水が必要であるが、最高回転数が150r/minと低い全自動洗濯機の場合は、給水口12bから吐出される水の大部分が下方へ流下し回転翼8a上に落ちるため、停止状態および極低速回転での給水は不要である。なお、この給水開始時および終了時の槽回転数については水跳ねと汚れ落ちの両面からの判断で構造に合わせて調整する必要がある。   FIG. 9 is a diagram showing the change in the number of rotations of the washing and dewatering tank 8 and the water supply timing. The washing and dewatering tank 8 is accelerated to about 100 r / min by right rotation, and then the rotational speed is increased to increase the rotation to about 150 r / min and the operation to decelerate to 100 r / min is repeated multiple times. After that, the rotation is stopped, the washing and dewatering tank 8 is left-rotated, and the number of rotations is changed similarly to the right rotation. Water supply is performed while the rotation speed of the washing and dewatering tank is rising from 100 r / min to 150 r / min. In the case of a vertical washer, the maximum rotation speed is as high as 800 to 900 r / min, so it is necessary to supply water in the stopped state (0 r / min) to wash the upper part of the rotor 8a and the lower part of the washing and dewatering tank 8. However, in the case of a full-automatic washing machine with a low maximum rotation speed of 150 r / min, most of the water discharged from the water supply port 12b flows downward and falls on the rotary wing 8a, so the stopped state and extremely low speed Water supply by rotation is unnecessary. The tank rotation speed at the start and end of the water supply needs to be adjusted in accordance with the structure based on the judgment from both the water splash and the dirt removal.

また給水方法は、縦型洗乾機と同様、水圧が高い場合は間欠にしたり、あるいは給水時間や給水回数を減らす、一方水圧が低い場合は連続にしたり、給水時間や給水回数を増やすなどの対応により、使用水量を水圧によらず一定範囲内に抑えつつ、汚れ落ちも一定レベルを保つようにする。   In the same way as vertical washers, water supply method is intermittent when water pressure is high, or it reduces water supply time and frequency, while it is continuous when water pressure is low, and it increases water supply time and frequency. Correspondingly, the amount of water used should be kept within a certain range regardless of the water pressure, and the dirt removal should also be kept at a certain level.

なお、排水弁14は縦型洗乾機と同様コース運転中は開弁したままで常に排水状態とする。   The drainage valve 14 is always in a draining state as it is open during course operation, as with the vertical type washer.

また、図6および図9は槽内洗浄のための動作であり、洗浄にポイントをおいているが、給水を停止した後に一定時間回転を継続し洗濯兼脱水槽8や回転翼8aの水滴を排除している。ただし、槽洗いコース後に洗濯運転をしない場合は、洗濯兼脱水槽8内に残る水滴をさらに減らした方が、外槽9や洗濯兼脱水槽8内の湿度を低い状態に保てる。このため、図10に示すように一連の槽洗い動作後に高速脱水を短時間行って水分をしっかり排除するようにしてもよい。   6 and 9 show the operation for cleaning the inside of the tank, and the point for cleaning is kept, but after stopping the water supply, the rotation is continued for a fixed time and the water droplets of the washing and dewatering tank 8 and the rotor blade 8a are kept. It is excluded. However, when the washing operation is not performed after the tank washing course, if the water droplets remaining in the washing and dewatering tank 8 are further reduced, the humidity in the outer tank 9 and the washing and dewatering tank 8 can be kept low. For this reason, as shown in FIG. 10, high-speed dewatering may be performed for a short time after a series of bath washing operations to firmly remove water.

次に、全自動洗濯機での別の実施形態について説明する。本実施形態は、洗濯兼脱水槽8の内壁面8cや回転翼80上の汚れだけでなく髪の毛などのごみの除去に適している。図11は、全自動洗濯機の内部構造を示すために筐体の一部および外槽を切断して示した右側断面図である。回転翼80の上面は、ベース面80aの中央が盛り上がったお椀状でその上に複数個の放射状の***部80bが形成されている。ベース面上には水抜きのための多数の貫通孔81が設けられている。給水ボックス12aの底面に設けた給水口12bは、開口方向が異なる3種類の給水口から成っている。1つ目はほぼ鉛直方向に開けられた給水口12b1であり、ここからの水41はほぼ真下に流下し、回転翼80の外周近傍に落下し、回転翼80の上面を洗浄するとともに、飛び跳ねて外周壁8cの下部を濡らす。2つ目は回転翼80の略中心に向かい開口した給水口12b2であり、ここからの水42は回転翼80の半径の半分より内側に落下し、ベース面80a内側の外周に向かい低くなる傾斜面80a1に沿って外周側に流れる。3つ目は流体バランサ8dの上面8d2に向かい開口した給水口12b3であり、ここからの水43は流体バランサ8dの上面8d2に落下し、流体バランサ8bの内周面8b1から洗濯兼脱水槽8の8cを流下する。流体バランサ8dの上面8d2には凸状の円環リブ8d3が形成されており、流下した水43が外周側に流れないようになっている。   Next, another embodiment of the fully automatic washing machine will be described. The present embodiment is suitable for removing dirt such as hair as well as dirt on the inner wall surface 8c of the washing and dewatering tank 8 and the rotary wings 80. FIG. 11 is a right side cross-sectional view showing a part of the housing and the outer tub in a cutaway view to show the internal structure of the full-automatic washing machine. The upper surface of the rotary wing 80 is in the shape of a bowl in which the center of the base surface 80a is raised, and a plurality of radial bumps 80b are formed thereon. A large number of through holes 81 for draining are provided on the base surface. The water supply port 12b provided on the bottom surface of the water supply box 12a includes three types of water supply ports having different opening directions. The first one is a water inlet 12b1 opened in a substantially vertical direction, and water 41 from here flows down almost directly and falls near the outer periphery of the rotary wing 80 to clean the upper surface of the rotary wing 80 and jump Wet the lower part of the outer peripheral wall 8c. The second is a water inlet 12b2 opened toward the approximate center of the rotary wing 80, and the water 42 from here falls inward from a half of the radius of the rotary wing 80 and slopes downward toward the outer periphery inside the base surface 80a. It flows to the outer peripheral side along the surface 80a1. The third one is the water supply port 12b3 opened toward the upper surface 8d2 of the fluid balancer 8d, and the water 43 from here falls to the upper surface 8d2 of the fluid balancer 8d and the washing and dewatering tank 8 from the inner peripheral surface 8b1 of the fluid balancer 8b. Flow down 8c. A convex annular rib 8d3 is formed on the upper surface 8d2 of the fluid balancer 8d so that the flowed-down water 43 does not flow to the outer peripheral side.

図12は、水43が落下する部分の槽カバー9bの形状を示す平面図である。槽カバー9bに切欠き部9b1(この例では円弧状の切欠き)を設け、水43が流体バランサ8dの上面8b2に直接落下するようにしてある。また、切欠き部には上方に伸びる壁9b2を設けてある。これは、流体バランサ8dの上面8d2から水が跳ねて槽カバー9b上に漏れないようにするためである。   FIG. 12 is a plan view showing the shape of the tank cover 9b in the portion where the water 43 falls. The tank cover 9b is provided with a notch 9b1 (an arc-shaped notch in this example) so that the water 43 falls directly on the upper surface 8b2 of the fluid balancer 8d. Further, the notch portion is provided with a wall 9b2 extending upward. This is to prevent water from splashing from the upper surface 8d2 of the fluid balancer 8d and leaking onto the tank cover 9b.

図13は、洗濯兼脱水槽8の回転数の変化と給水タイミングを示す図である。洗濯兼脱水槽を右回転させ、おおよそ10r/minになったら回転数を保持して給水を開始する。流体バランサ8dに落下した給水43は流体バランサ8dの内周面8b1を流下し、洗濯兼脱水槽8の外周壁8cに伝わり、そのまま外周壁8cに沿って流下する。この回転数の保持時間を20〜40秒間(時間は水道水圧により変更する)とすることにより、外周壁8cの円筒面全体に水を流下させることができるため、外周壁8cに付着していた小さなゴミだけでなく髪の毛などの比較的大きなゴミも下部に流し落とされる。ゴミの一部は回転翼80と外周壁8cとのすき間82から外槽9に流れ出る。図8の実施形態では、空気の流れによる圧力差で水を流体バランサ8dの内周面8d1にかけるようにしていたが、本実施形態では直接流体バランサ8dに水をかけているため、より確実に外周壁8cに水を流下させることができ、髪の毛のような大きめのゴミを洗い流すことが可能となる。   FIG. 13 is a view showing the change in the number of rotations of the washing and dewatering tank 8 and the water supply timing. Turn the washing and dewatering tank to the right and when it reaches approximately 10 r / min, maintain the rotation speed and start water supply. The water supply 43 dropped to the fluid balancer 8d flows down the inner peripheral surface 8b1 of the fluid balancer 8d, is transmitted to the outer peripheral wall 8c of the washing and dehydration tank 8, and flows down along the outer peripheral wall 8c. By holding the rotation speed for 20 to 40 seconds (time is changed by the tap water pressure), water can be made to flow down the entire cylindrical surface of the outer peripheral wall 8c, so it adheres to the outer peripheral wall 8c Not only small rubbish but also relatively large rubbish such as hair is washed down to the bottom. A part of the dust flows out of the gap 82 between the rotor 80 and the outer peripheral wall 8 c into the outer tank 9. In the embodiment of FIG. 8, water is applied to the inner circumferential surface 8d1 of the fluid balancer 8d by a pressure difference due to the flow of air, but in the present embodiment, water is directly applied to the fluid balancer 8d. Water can be allowed to flow down the outer peripheral wall 8c, and it becomes possible to wash away large trash such as hair.

その後、いったん給水を停止し、洗濯兼脱水槽8の回転数を100r/minまで上げた後、回転数の上昇速度を高くして100r/minから150r/minに上昇させながら給水を行う。このとき、回転翼80の半径の半分より内側に落下した水42は遠心力で回転翼80のベース面80aに沿って外側へと流れ、この水の流れに乗って、回転翼80上のゴミが回転翼80と外周壁8cとのすき間82から外槽9に流れ出る。また、低速(10r/min)回転時の給水で外周壁8cの下部に下がってきたゴミの一部も、回転翼80の外周近傍に落下した水41が回転翼80のベース面80aや***部80bで反射して外周壁8cの下部に当ることにより、回転翼80と外周壁8cとのすき間82から流れ出る水とともに洗濯兼脱水槽8から流れ出る。給水を停止し、洗濯兼脱水槽8の回転数は150r/minで短時間(10秒程度)保持した後、回転を停止する。その後左回転させ、上述の右回転と同様の動作を行う。この後、洗濯兼脱水槽8内に残る水滴をさらに減らすことを目的に高速脱水を行ってもよい。   Thereafter, the water supply is once stopped, the rotation speed of the washing and dewatering tank 8 is increased to 100 r / min, and the water supply is performed while increasing the rising speed of the rotation speed from 100 r / min to 150 r / min. At this time, the water 42 dropped inward from the half of the radius of the rotary vane 80 flows outward along the base surface 80 a of the rotary wing 80 by centrifugal force, rides on this water flow, and the dust on the rotary wing 80 Flows out of the gap 82 between the rotor 80 and the outer peripheral wall 8c to the outer tank 9. Also, part of the dust that has fallen to the lower part of the outer peripheral wall 8c due to water supply at low speed (10 r / min), the water 41 that has dropped to the vicinity of the outer periphery of the rotary wing 80 By reflecting at 80b and hitting the lower part of the outer peripheral wall 8c, it flows out of the washing and dewatering tank 8 together with the water flowing out of the gap 82 between the rotor 80 and the outer peripheral wall 8c. After the water supply is stopped and the rotation speed of the washing and dewatering tank 8 is maintained at 150 r / min for a short time (about 10 seconds), the rotation is stopped. Thereafter, it is left-rotated to perform the same operation as the above-mentioned right-rotation. After this, high-speed dewatering may be performed for the purpose of further reducing water droplets remaining in the washing and dewatering tank 8.

また、流体バランサ8dの下面の形状を図14に示すよう内周面8d1と外周壁8cをスムーズに接続する傾斜面8d4としてもよい。こうすることで流体バランサ内周面8d1を流下する水43が内周面8d1下部で剥離して外周壁8cに到達せずに流下することが防げるため、水43を無駄なく外周壁8cへ導くことができ、外周壁8cを洗う水量を確保できる。   Further, as shown in FIG. 14, the shape of the lower surface of the fluid balancer 8d may be an inclined surface 8d4 that smoothly connects the inner peripheral surface 8d1 and the outer peripheral wall 8c. As a result, the water 43 flowing down the fluid balancer inner peripheral surface 8d1 is prevented from peeling off at the lower portion of the inner peripheral surface 8d1 and flowing down without reaching the outer peripheral wall 8c. Thus, the amount of water to wash the outer peripheral wall 8c can be secured.

本実施形態では、水43を流体バランサ8の上面8d2に当てるようにしたが、内周面8d1に直接当てるようにしてもよい。さらに、槽洗い性能を高めるために、給水口9gや12bの形状を、洗濯兼脱水槽8の外周壁8cの内側に水が直接当るようにすると、より効率よく洗濯兼脱水槽8の内面を清掃できる。   In the present embodiment, the water 43 is applied to the upper surface 8d2 of the fluid balancer 8, but may be applied directly to the inner circumferential surface 8d1. Furthermore, if water is directly applied to the inside of the outer peripheral wall 8c of the washing and dewatering tank 8 in order to improve the tank washing performance, the inner surface of the washing and dewatering tank 8 can be more efficiently It can be cleaned.
